AN UPDATE (3 March 2008):Hello, 
Playmofriends ...  

After looking carefully at all the hairstyles, clothing, etc. of Playmobil's 
North American Indians, it appears that they really fit into only 
three of the 
nine groups:
The largest Playmobil group are the 
Plains Indians. They were nomadic buffalo hunters who followed the buffalo herds. After the arrival of the European horses, they became very skilled horsemen. The 
Sioux seem to be the best represented Indians produced by Playmobil.
The second largest Playmobil group are the 
Southwest Indians. They were farmers and shepherds as well as hunters. The Playmobil figures representing the 
Southwest Indians look somewhat similar to the 
Apaches.
The third largest Playmobil group are the 
Arctic Indians which Playmobil depicted rather well with their 
Eskimo theme.
The 
Northwest Coast Indians appear to be really only represented by their Playmobil 
totem poles.
Unfortunately, I do not have any of my Playmobil Indians with me. However, if someone wants to assemble a typical Playmobil 
Sioux or 
Apache, I would be happy to make some suggestions as to which parts to use. 
BTW, the politically correct terms for North American Indians, or Amerindians, are now 
Native Americans for Indians living in the United States and 
First Nations People for Indians living in Canada.
When I was a kid playing "Cowboys and Indians," there were almost no "Eastern Indians" from India living in Fort Lauderdale. So, when we took turns playing either the "Cowboys" or the "Indians," there was little chance for confusion. Nowadays, it does seem to make more sense to call our native populations by something that's more easily identifiable.
All the best,
Richard
